4bananas and 3 peaches cost $10. we can represent this information as 4x +3y = $10. the x represents the cost of bananas and the y represents the cost of peaches.
a) find an equation for 1 banana and 2 peaches cost $5
b) with the two equations, use a matrix method on your calculator to determine the cost of a banana and the cost of a peach.

Find the greatest common factor of the followig monomials 21u^5v,3u^4v^6, and 3u^2v^5

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
